Treasure, there is little treasure I keep.

some odds and ends, a trinket or two,

but there is one thing, that out does most.

It's a simple thing, a little thing.

yet it boasts among the most treasured.

A key.  a simple key, not to the heart, no.

For those keys are given and taken,

as quickly as a summer rain.

no, this key is not so easily given,

neither is it easily shared.

It opens the door to my innermost sanctum

It is the key to my mind, my thoughts,

to my desires, my wants.

It is my last defense,

my last refuge.
